Choose the Write Words
My friend Sandra Merville Hart writes historical fiction and wrote piece on researching words that are appropriate for her characters to say in the time period she is writing about. She describes how modern words and phrases in the mouths of characters living hundreds of years ago will ruin the effect the author wants to create.
She lists two sites that help authors research words and phrases. For example, it is “okay” for Civil War characters to say something is “okay”. But those characters can’t “okay” something because using “okay” as a verb wasn’t done until 1888.
